In addition, such redox-active organometallic dendrimers are interesting materials with which to modify electrode surfaces. Applications of these dendrimer modified electrodes in the fields of amperometric and potentiometric biosensors, molecular recognition, as well as in electrocatalysis and photoelectrochemistry, clearly represent interesting areas of future research. 

An interesting investigation concerns the use of PPI dendrimers functionalized with both ferrocene and cobaltocenium moieities for glucose biosensor [105, 127], Such dendrimers can exhibit a double function while the ferrocene units act as mediators in enzymatic processes under anaerobic conditions, the cobaltocenium moieties take part in the electrocatalysis in the presence of oxygen. Another major advantage cited of these electrodes is that a large amount of enzyme can be immobilized due to electrostatic interactions between the positive...
